计算表中的金额 (td)

Question

我正在创建一个网络应用程序，我在其中获取数据（员工的费用）。

我想计算所有td的金额并打印出来。

我正在使用 angularjs 来获取数据。

这是我的桌子：

<tr>
                <th colspan="2" style="border:1px solid black">Payment Id</th>
                <th colspan="2" style="border:1px solid black">Date Of Issue</th>
                <th colspan="2" style="border:1px solid black">Date Of Trainer</th>
                <th colspan="1" style="border:1px solid black">Training Id</th>
                <th colspan="2" style="border:1px solid black">Payment Mode</th>
                <th colspan="2" style="border:1px solid black">Cheque/ UTR no</th>
                <th style="border:1px solid black">Amount</th>
            </tr>
            <tr ng-repeat="i in getexpenseinfo">
                <td colspan="2" style="border:1px solid black">{{i.paymentid}}</td>
                <td colspan="2" style="border:1px solid black">{{i.dateofissue}}</td>
                <td colspan="2" style="border:1px solid black">{{i.dateoftransfer}}</td>
                <td colspan="1" style="border:1px solid black">{{i.trainingid}}</td>
                <td colspan="2" style="border:1px solid black">{{i.paymentmode}}</td>
                <td colspan="2" style="border:1px solid black">{{i.chequeno}}</td>
                <td style="border:1px solid black">{{i.amount}}</td>
            </tr>

{{i.amount}} 列正在获取花费在费用上的金额，这里是我的控制器

$http.get('/paymentrpt.asmx/expenseinforpt', {
                params: {
                    datefrm: $scope.datefrm,
                    dateto: $scope.dateto,
                    empname: $scope.emp
                }
            }).then(function (response) {

                $scope.getexpenseinfo = response.data.info;
                $scope.pageload = false;
            });

以及我正在获取数据的网络服务：

[WebMethod]
        [ScriptMethod(UseHttpGet = true)]
        public void expenseinforpt(string datefrm, string dateto, string empname)
        {
            List<object> expenseinfo = new List<object>();
            SqlCommand cmd = new SqlCommand("prolltexpense", con);
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Connection = con;
            con.Open();
            SqlParameter[] param = {
                new SqlParameter("@from",datefrm),
                new SqlParameter("@to",dateto),
                new SqlParameter("@trainer",empname)
            };
            cmd.Parameters.AddRange(param);
            SqlDataReader dr = cmd.ExecuteReader();
            while (dr.Read())
            {
                expenseinfo.Add(new
                {
                    trainingno = dr["trainingno"].ToString(),
                    expenseno=dr["expenseno"].ToString(),
                    expensehead=dr["expensehead"].ToString(),
                    amount=dr["amt"].ToString(),
                    remark=dr["remark"].ToString(),
                    claim=dr["gigeraccount1"].ToString()
                });
            }
            var json = js.Serialize(expenseinfo);
            Context.Response.Write("{" + '"' + "info" + '"' + ":" + json + "}");
            con.Close();
        }

这是我从中获取金额的存储过程：

CREATE PROCEDURE prolltexpense (@from varchar(50),@to varchar(50),@trainer varchar(50))  

AS  
BEGIN  
select expense.trainingno,expense.expenseno,expense.expensehead,expense.amt,expense.remark,(case when expense.gigeraccount=1 then 'YES' when expense.gigeraccount=0 then 'NO' end) as gigeraccount1 from instructoreexpense left outer join sonvininsert on son
vininsert.sonvinid=instructoreexpense.sonvinid left outer join finalinstructoreexpense on finalinstructoreexpense.sonvinid=instructoreexpense.sonvinid join expense on sonvininsert.trainingno=expense.trainingno  where sonvininsert.date between convert(date
time,@from,105) and convert(datetime,@to,105) and sonvininsert.trainer=@trainer  order by sonvininsert.date  

END

如果要计算桌子的金额，我需要做什么？

这就是我的桌子的样子：

Training Id Expense No. Expense Head    Amount  Remark  Claim
16100800002 16100800002001  Conveyance  20  Kurla to Mumbra Return by train NO

Answer 1

我不知道 angularjs，但你可以从 sql-server 轻松完成

select sum (expense.amt) as totalamt
 from instructoreexpense left outer join sonvininsert on 
sonvininsert.sonvinid=instructoreexpense.sonvinid left outer join finalinstructoreexpense on 
finalinstructoreexpense.sonvinid=instructoreexpense.sonvinid join expense 
on sonvininsert.trainingno=expense.trainingno   where sonvininsert.date 
between convert(datetime,@from,105) 
and convert(datetime,@to,105) and sonvininsert.trainer=@trainer

如果它给你错误，请告诉我，因为我使用你给定的代码，我不知道你的 sql 中的费用是 int 还是 varchar
